Transport of contaminated gas and dust in high-rise apartment buildings.

Jacques Whitford Environment Limited (JWEL) and Morrison Hershfield Limited (MH) have completed a research project investigating the level of risk associated with soil gases and dust in high-rise apartment buildings. The research was conducted in response to a request for proposals issued by the Canada Mortgage Housing Corporation (CMHC). The study investigated the hypothesis that the risk associated with gas and dust from contaminated lands can be reduced for residents of high-rise apartment buildings compared to residents of single-unit or low-rise residential structures . The study was conducted using a literature search to examine the risk associated with fugitive dust in high-rise apartment buildings, and tracer gases to examine transfer paths of gaseous phase contaminants and the effects of ventilation systems.
